Abstract

São descritos três casos de leishmaniose cutânea em cobaias (Cavia porcellus) machos de dois anos de idade que eram criadas como animais de estimação. As lesões macroscópicas eram semelhantes em duas cobaias e consistiam de nódulos cutâneos ulcerados no aspecto dorsal do pavilhão auricular de ambas as orelhas. Na outra cobaia, a lesão consistia de engrossamentos irregulares na pele do escroto que apareceram após uma orquiectomia realizada dois meses antes. A histopatologia era semelhante nos três casos e consistia de acentuada dermatite granulomatosa, com ulceração e numerosas formas protozoárias amastigotas no citoplasma de macrófagos, sugestivas de Leishmania sp. A microscopia eletrônica confirmou o diagnóstico de leishmaniose.Three cases of cutaneous leishmaniasis in three two-year-old male guinea pigs (Cavia porcellus) raised as pets are described. Gross lesions were similar in two of the guinea pigs and consisted of raised and ulcerated cutaneous nodules in the dorsal aspect of the pinna of both ears. In another guinea pig the lesion consisted of irregular thickenning in the skin of the scrotum which followed an orchiectomy performed two months before. Histopathology was similar in the three cases and consisted of severe diffuse granulomatous dermatitis with ulceration and numerous intrahistiocytic protozoal amastigotes resembling Leishmania sp. Electron microscopy confirmed the diagnosis of leishmaniasis.
